69The nervous system consists of nerve cells or neurons, which can transmit information in the form of electrical signals to our sense organs. Neurons generally are not a good electrical conductor; however, they have elaborate mechanisms for generating electrical signals by eliminating negative resting potentials. Negative resting potentials occur due to the accumulation of more sodium ions outside the cell than potassium ions inside the cell. The resting potential is determined by the selective permeability of the membrane to different types of charged particles, and the uneven distribution of the particles between the inside and outside of a cell. The action potential is the electrical impulses used as communicative agents that connect cells with excitable membranes, such as the neurons, muscles cells, and endocrine cells. Action potentials, which are transmitted along the axons, abolish the negative resting potential by making the transmembrane potential transiently positive through electrochemical gradients of ions. The artefact shows the ‘jumping’ action of an electric current from one light to another. This action mimics the ‘bouncing’ action of electrical signals containing information, upon the arrival of an action potential, from one axon to another in the nervous system. When an action potential has occurred at the initial node, a local current causes neighbouring sections to depolarise. Ion pumps at the axon cell membrane ensure the distribution of ions is normalised and ready for the next threshold.The Bouncy BeamMariatulqabtiah Abdul Razak and Ruqayyah Ainul Bashirah707172
